Eggs from individual Atlantic salmon (Salmo salar) were
hatched in a Californian hatching system with and without
an astro-turf artificial substrate and growth during the first
200 days following hatching was investigated.
The astro-turf promoted yolk absorption rate, yolk conversion
efficiency and growth during the hatchery incubation
and feeding. However, yolk absorption rate was also dependent
on yolk weight at hatching with highest absorption rate in
alevins with high yolk weight. Due to an increasing variance,
the weight difference between the systems was no longer significant
at the termination of the experiment.
